Buying your booster assembly and line set together is the best way to ensure you don't get stuck with incompatible lines and proprtioning valve. USA made stainless steel brake lines that are designed to be used with the included booster, master cylinder and valve. This kit can work with disc/drum or disc/disc brake setups and includes a Chrome 8" Dual Brake Booster Assembly with 1" Bore Master and Adjustable Prop Valve & Stainless Front Brake Line Kit and Front to Rear Line, Booster Mounting Brackets, Rod & Clevis and all necessary hardware.
Over the years we have found that the included 1" bore master cylinder works well in many power disc/drum and power disc/disc applications. Having said that many factors go into what bore size will work best, including pedal ratio, engine vacuum, piston quantity and diameter, etc. You may want to contact the manufacture of your calipers for a bore diameter recommendation.
